Enum RerankError 

pub enum RerankError {
    EmptyCandidates,
    TooManyCandidates {
        actual: usize,
        limit: usize,
    },
    Engine(String),
    SignalError(String, String),
    Config(String),
    Api(String),
    WeightSumInvalid(f32),
    MissingQueryEmbedding,
}

重排序错误

Variants

EmptyCandidates

候选项列表为空，无法执行重排序

TooManyCandidates

候选项数量超过限制

Fields

actual: usize

实际候选项数量

limit: usize

允许的最大候选项数量

Engine(String)

重排序引擎内部错误

SignalError(String, String)

信号计算过程中发生错误

Config(String)

配置参数无效

Api(String)

远程 API 调用失败

WeightSumInvalid(f32)

信号权重之和不为 1.0

MissingQueryEmbedding

需要 query embedding 但未提供（vector_similarity 信号需要外部传入）

Implementations

impl RerankError

pub fn is_retryable(&self) -> bool

判断错误是否可重试

返回 true 表示该错误为临时性错误（如 API 调用失败、引擎内部错误）， 调用方可以安全地重试操作。返回 false 表示该错误不可恢复。

Trait Implementations

impl Debug for RerankError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for RerankError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for RerankError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
